Starring Darsheel Safary of the 'Tare Zameen Par' fame, the film's pivotal essence is a unique brother-sister relationship. Priyadarshan has very perceptively carved out the innocent and poignant story of two siblings and the dilemmas they face in life and how they fight their way to overcome it. 'Bumm Bumm Bole' is sure to bring out the hidden child inside all of us... Two little feet, one long journey.

The movie also stars Ziyah as Rim Zim who plays the sibling and Atul Kulkarni as Khogiram and Rituparna Sengupta as Khogiram's wife.
